My invention relates to handles of the v l forming theV locking spurs.

class used upon spades, shovels and some a suitable tool for other toolswhich consistof a bifurcated element having its branches connected attheir ends by a transverse holding or hand-gripping member, and ofl thetype of such handles in which the forked member is formed of sheet metalstamped into suitable form to form at its base a stale socket engaging awooden stale member and having the two branches formed with a Vpair ofterminal grip sockets arranged to be connected to a wooden cross-gripwhich extends between them. The object of my invention is to provideimproved means for locking the wooden grip member in the sockets in asimple, sightly and secure manner, so that the appearance of the handlewill not be marred, yet the grip member will be so effectively held thatit cannot get loose and chatter, even after considerable usage. It hasbeen found that the various forms of locking lugs, fins, or otherprotuberant members heretofore employed in the prior art, so far asknown to me, are all subject to becoming loose and chatteringrunder anyusage which produces frequent or constant jarring of the handle, and theobject of my invention is to obviate this defect in a desirable andeffective manner. To, this end I have devised the tool handlehereinafter described in detail7 the essential elements of my inventionbeing more particularly pointed out in the appended claims.

Figure l of the drawings illustrates a tool handle having a bifurcatedsheet metal member engaging a wooden grip and provided with lockingmeans embodying my invention;

Fig. 2 is an end or face view of the out-V side of one of the gripsockets, showings the shape of the cut which is made in forming thelocking spurs;

Fig. 3 is a fragmentaryjvertical diametrical section of the same portionof the handle as that illustrated in Fig. 2, showing the locking spursbent inwardly and imbedded in the grip, the plane of the section beingindicated by the dotted line 3 3 of Fig. l; and

Like Vreference characters indicate like4 Y parts in all the igures ofthe, drawing. j

The exact pattern of the sheet metal member of a tool handle tol which'my inf vention is` applicable may varyin several respects, solong asitis formedtoprovide Y at the ends of the two branches 1-l of the handleinwardly-facing cup-shaped4 grip sockets .f-f2. The ends of the woodengrip 8 of., the. handle are these sockets, and thewhole secured firmlyand rigidly together by a bolt 4. extending longitudinally through thegrip` and riveted at its ends as securely as possible to said lPreferably,"and according to com-` sockets. monV practice, the boltextends through the gripeccentrically of the sockets, as illustrated, sothat .itis incapable of rotating in the sockets. i

vThe handle having the parts assembled thus 'far described, the areafterwards locked been constructed and together in av novel manner nowto be described, to forni the By meansof a suitable Fig.` 4, the metalof each:l upon two parallel linesg co c completed handle.

punching tool a, see grip socket is out and a transverse central line,approximately in the shape of the letter H, as illustrated in Fig. 2, solas to yprovide two rectangular spurs 5 5 j lying between the parallelcuts and having their free edge directed'towards each other from uncutmetal, and as these spurs are cut and formed they are forced or drivendown into the wood by continued application of the tool until they areimbedded in the wood as a pronounced angle to the original posi` tion ofthe metal. Both grip locks may conveniently be made at the same time bymeans of a suitable press.

It has been found that the locked engagement of the grip sockets to thewooden grip thus provided forms a much more secure and permanentconnection in respect to maintaining tightness and prevention of thechattering arising from jarring and severe usage than any of the more orless rounded or conseated snugly j within* and secured together asgripsockets and grip opposite bases connected to the veX forms ofprojections heretofore employed. The square-cut side edges and ends ofthe two spurs tend rather to become imbedded the more firmly in the woodof the grip by any expansion of the wood which may occurvfalong theirside edges 'and be` tween their ends subsequent to application of thepressure by which the spurs are forced i into place, than to becomeloose.

I claim:A v y 1. In ahandle of' they typeV described including abifurcated sheet metal member formed with terminal opposed grip-sockets,a transverse wooden grip and a bolt extending longitudinally throughsaid grip arranged to secure said grip-betweensaid sockets, means forlocking said grip in said grip-,sockets comprising` a pair ofrectangular spurs struck inwardly from said sockets and imbedded in theadjacent end of the i wooden grip, said spurs being cut uponparallelsidelines and a transverse intermediate line defining the ends of thespurs.

2. In a handle of the type described including arms provided withterminal sheet metal grip-sockets opposed to eachother, a transversegrip formed of wood and having its'ends positioned in said sockets,means for securingy the sockets to the grip to prevent separation -ofthesame, and locking means comprising adj a'cent convergingy spurs struckinwardly from each sheetmetal sockety and compressingv the wood underthem.

3. A handle of the type described including arms provided with terminalsheet metal gripsockets opposed to each other, Va transverse woodengrip, a's'ecuring boltextend ing through the sockets andthe grip, and apairof spurs -struck inwardly from one 'of the sheet metal sockets,

so that they are opposed to each other, their lines of bending areparallel, and theirI edges are substantially radial with respect tothegrips.` o f Iny testimony whereof, Il have subscribed my name.
